摘要： A process of manual, semi-automatic and fully-automated integration of discrete components into a container that results in fast, reliable, cost-effective, and scalable production of composite containers is disclosed. The process can be embodied in manufacturing equipment that has a series of stations and may be called an assembly device. The equipment can produce containers, tubs, canisters, cartridges, etc. which are easily separated into different bio-degradable or compostable parts. Other container types are possible and are contemplated.

摘要： An injecting/blowing device includes a mold for injecting a thin-walled hollow preform capable of being transformed into a more voluminous hollow body. The mold includes a counter mold defining a cavity, a cure located in the cavity, and a preform impression located between the counter mold inner surface and the core which will receive the melt, at least two main preferential flow channels or at least two secondary preferential flow channels having a recessed zone at the surface of the core and the inner surface of the cavity. The main flow channels are located only at the impression zone corresponding to the zone for transforming the preform, and in the optional secondary flow channels are flow channels discontinuous from the main flow channel.

摘要： A parison is described, as also is a method for the production of plastics bottles, in particular PET bottles, this having a rigid, substantially elongate body (2), which has a base (5) at one of its ends. At its opposite end, the body (2) of the parison (1) adjoins a neck section (3) which has been provided with a pouring aperture (6) and which is separated from the body (2) via a radially protruding, flange-like support ring (4), and which has a parison shoulder (A) below the support ring (4). The parison (1) has an external diameter of from 17.4 mm to 21.4 mm measured at the transition of the body (2) to the base (5), its wall thickness at that point being from 3.4 mm to 4.4 mm. The parison (1) also has a wall thickness of from 1.4 mm to 2.2 mm at the parison shoulder (A). The external diameter of the parison shoulder (A) has been judged in such a way that its separation (d) from the blow molding wall (12) is from 1.2 mm to 3 mm when the parison (1) is inserted into the blow mold (10).

摘要： A finish for a plastic container and a preform adapted to be molded into the plastic container. The finish and the preform include an upper portion having a mouth defining an opening into the container. At least one groove is defined around a radial sidewall of the upper portion. The groove slopes gradually downward along the radial sidewall to a terminal end having a first groove depth at a groove entrance and a second groove depth after a predetermined amount of groove travel. The second groove depth being greater than the first groove depth.

摘要： The present invention provides a multilayer plastic bottle comprising layers of PET and a polyamide such as, for example, MXD6, that is free from occurrence of delamination upon dropping or upon exposure to impact. The present inventors have found that when forming a barrier layer containing an adhesion promoting agent according to the present invention, an impact energy applied to the barrier layer is well reduced and the resultant multilayer bottle is improved in interlaminar bonding strength and prevented from suffering from delamination upon dropping, etc.
